You'll work closely with our cloud partners on capabilities we need that don't exist yet, and with internal Compute, Inference, and Security teams to make "which cloud is this running on?" a question most engineers at Anthropic never have to ask.
Staff Software Engineer, Simd Kernels D-MatrixStaff Software Engineer, Simd KernelsSanta Clara, CAYou have experience building software kernels for modern hardware architectures and understand how to map algorithms and AI‑framework computational graphs onto those architectures. What you will bring: Minimum: MS or PhD in computer engineering, math, physics, or a related degree with 5+ years of industry experience.
Staff Software Engineer, Web Platform AnthropicStaff Software Engineer, Web PlatformSan Francisco, CAThis means designing and shipping shared components and design-system-level abstractions, evolving the backend-for-frontend (BFF) APIs that power our client applications, and improving the build, deploy, and observability systems that keep Claude.ai running smoothly across surfaces. This is a great fit if you care deeply about developer experience and want your engineering work to have outsized leverage: instead of shipping one feature, you're building the tools and systems that make dozens of features possible.
NewStaff+ Software Engineer, Claude Managed Agents AnthropicStaff+ Software Engineer, Claude Managed AgentsSan Francisco, CAInstead of every developer hand-rolling an agent loop, sandboxed execution, state management, credential handling, and error recovery - and reworking all of it with every model release - Managed Agents pairs an Anthropic-built agent harness with production infrastructure for sessions, environments, tools, memory, and permissions, exposed through a small set of composable APIs designed to stay stable as models and harnesses evolve. You'll ship the capabilities that raise the ceiling on what those agents can do: outcome-driven execution where developers specify success criteria and a budget and Claude iterates until it gets there, multi-agent orchestration, memory, and the observability and tracing that make long-running agents debuggable.
